Lying on your back with your head resting on the neck-cushion of an abdominal trainer.
Bending your hips and knees, raise both legs up towards your chest. Lift up your head and shoulders while your arms exert as much pressure on the handles as required to carry your head forward. Roll up in a smooth, controlled movement, then return to the starting position, controlling the movement back down. Maintain hips and knees in raised position throughout. Keep your neck relaxed throughout. Rest then repeat.
